An open model | United States | 2009 to today
Lives cut short, years with depression, medical bills, and missed work.
The comparison is a United States where social media did not expand beyond its 2009 reach. We cannot observe that other world. The total changes when you change the assumptions.
Review the assumptions or start with a preset.
This setting includes about 8,910 deaths and 30 million years lived with depression.
Observed change×Share caused by social media×Public value
Research measures parts of the observed change. You choose the uncertain share. Public guidance and cost studies convert the result into dollars.
Model inputs
Move any slider. The sensitivity range shows how much that choice can change the total.
Each normal curve is a visual guide to the model range. It does not show the probability of any value.
Choose a study when its finding measures this input. Adjust the value to test a different assumption. Watch the estimate and formula change together.

Current result
This model output compares assumptions. No one measured this loss, and it does not describe one person's experience.
Method & sources
The calculator adds the cost of lives lost, years lived with depression, healthcare, and missed work. You can change every part.
Limitations
Evidence index
The output is an illustrative cumulative estimate for the United States since 2009. It combines editable assumptions about lives lost, years with depression, healthcare spending, and missed work.
A source's reported finding sets an input only when it measures the same quantity. Other sources provide context. Open any source to check the difference.
What surveys show
Around 2012, more teenagers began reporting serious sadness and other mental health problems. Smartphones and social media also became a bigger part of daily life.
These changes happened at about the same time. That does not prove that one caused the other. Researchers need careful comparisons to test possible causes.
Researchers use several checks to study the change.
A real change should appear in several trusted sources. One chart is not enough.
Researchers compare people who got access earlier with similar people who got access later.
Change each assumption and see how much the final estimate moves.
Primary evidence
This calculator does not give a final verdict. It shows the choices behind the estimate so you can test them yourself.
